PURPOSE: Although the potential for complications following endovascular aneurysm repair (EVAR) mandates lifetime follow-up, non-compliance with follow-up has been shown to be as high as 57%. We sought to investigate the incidence of non-compliance with follow up in our patient population and to identify risk factors associated with this, in order to allow implementation of targeted strategies to prevent loss to follow up. METHODOLOGY: We carried out a review of consecutive patients undergoing EVAR at two Sydney hospitals between 1995 and 2015...

Practitioners of endovascular surgery have historically utilized two-dimensional (2D) intraoperative fluoroscopic imaging, with intra-vascular contrast opacification, to treat complex three-dimensional (3D) pathology. Recently, major technical developments in intraoperative imaging have made image fusion techniques possible: the creation of a 3D patient-specific vascular roadmap based on preoperative imaging which aligns with intraoperative fluoroscopy, with many potential benefits. First, a 3D model is segmented from preoperative imaging, typically a CT scan...

BACKGROUND: An anomalous muscle bundle crossing the right atrial cavity represents a pathological finding with unproved clinical significance. This congenital anomaly may be difficult to recognize via echocardiography and could be confused with other intra-cavitary lesions. METHODS: We report a case of a 53-year-old female presented to the cardio-vascular service with acute superior vena cava syndrome and sub-massive pulmonary embolism. RESULTS: The patient underwent venography confirming superior vena cava stenosis...

OBJECTIVE: Impaired microcirculation is associated with poor walking capacity in symptomatic peripheral artery disease (PAD) patients during treadmill test, however, this test does not simulate the efforts of daily walking of these patients. Thus, the aim of the study was to describe the microcirculation responses during six-minute walk test (6MWT) and to analyze the relationship between microcirculation indicators and walking impairment in symptomatic PAD patients. METHODS: Thirty-four patients were included (mean age = 67...

May-Thurner syndrome (MTS) is a rare cause of deep venous thrombosis (DVT) and occurs due to an anatomic anomaly which produces chronic compression of the left common iliac vein by the overlying right common iliac artery when it passes between the right common iliac artery and the spine. Prolonged compression on the vein potentiates thrombus formation by impairing the intima and by leading to the development of membranes within the lumen that may decrease and/or block venous flow. In this case presentation, we elaborate upon a case of a 43-year-old woman who presented with worsening left leg swelling and pain...

We report the case of a 70-year-old man with an asymptomatic, fast-growing, paraceliac penetrating aortic ulcer (PAU). Guidelines recommend endovascular repair if an asymptomatic PAU shows a mean growth rate ≥5 mm per year: this patient's maximum aortic diameter was 47 mm but had increased 10 mm in the previous year. The very short sealing zones required a custom-made stent-graft. A custom-made Relay stent-graft with a single celiac trunk fenestration, a superior mesenteric artery (SMA) scallop measured according to SMA ostium size, an uncovered distal stent, and 6-mm tapering was used with technical and clinical success...

BACKGROUND: To date , thoracic endovascular aortic repair (TEVAR) for type B aortic dissection is favorable, but TEVAR for type B IMH remains uncertain. There are numerous clinical (eg, refractory pain) and radiologic (eg, IMH thickness) factors that are reported to be associated with IMH progression, challenging the treatment for high-risk type B IMH with high risk factors in clinical practice. OBJECTIVE: To perform a systematic review of clinical studies to investigate outcomes of TEVAR+BMT and BMT in the treatment of high-risk type B IMH ...

Standard salvage procedures for occuluded autologous arteriovenous fistula (AVF) in a hemodialysis patient are endovascular and/or surgical therapy. When endovascular therapy and thrombectomy prove unsuccessful, it is most likely that creating a new AVF or arteriovenous graft will be considered. However, if the occuluded venous part is short, we have adopted an operative technique for repair of AVF by removal of the occluded short venous part and venovenous end-to-end anastomosis. To our knowledge, the efficacy and clinical course of restoration of AVF by the technique have not been reported to date...

Exostoses or osteochondromas are benign osseous tumors that develop on the bone surface and can be sporadic or hereditary. Their evolution is generally benign but they may be complicated in some patients by conflicts with the surrounding nervous or vascular structures, in particular arteries. We report a case of false aneurysm of the popliteal artery secondary to an isolated exostosis of the left femur in a 20-year-old young woman. A delay in the diagnosis allowed the development of the false aneurysm which was at the origin of a major venous compression...

OBJECTIVES: We recently described a pulsatile fresh frozen human cadaver model (PHCM) for training endovascular practitioners. This current study aims to assess the construct validity of PHCM; its ability to differentiate between participants of varying expertise. METHODS: 23 participants with varying endovascular experience (12 novice, 4 intermediate, 7 expert) were recruited. Each attempted catheterisation of the left renal artery on PHCM within 10 minutes under exam conditions...

Friedrich Wilhelm Nietzsche (Röcken 1844 -Weimar 1900), the philosopher that theorized the concept of "eternal recurrence", suffered lifelong of a multifaceted chronic illness, which started in paediatric age with severe headaches and ended with stroke at the age of 56. Even though in the last years many hypothetical diagnosis have been proposed, they all fail to explain the totality of clinical conditions that co-occurred in the philosopher's extremely challenging case, and debate on the matter is still open...

BACKGROUND: Patients with peripheral arterial disease (PAD) often have high comorbidity burden that may complicate post-interventional course and drive increased healthcare expenditures. Racial disparity had been observed in lower extremity revascularization (LER) patterns and outcomes. In 2014, Maryland adopted an all-payer rate setting system to limit the rising hospitalization costs. This resulted in an aggregate payment system in which hospital compensation takes place as an overall per capita expenditure for hospital services...

BACKGROUND: Patients with Stanford B aortic dissection usually complicated with sleep apnea syndrome. This condition always threatens the patients' respiration situation. In this study, we collected and analysis data of patients' peri-operative managements of Thoracic Endovascular Aortic Repair (TEVAR) for Stanford B Aortic Dissection (AD) complicated with Sleep Apnea Syndrome (SAS). Comparison has been made between these SAS patients and those who without SAS. METHODS: Between June 2013 and June 2014, the clinical data and outcomes of the Stanford B AD patients in the department of vascular surgery in the Second Xiangya Hospital were retrospectively reviewed and studied...

Cheong Jun Lee, Robert Cuff
Open conversion following endovascular aortic repair (EVAR) has inherent challenges particular to the device being explanted. The Nellix endograft is unlike any other device as it utilizes polymer filling of endobags within the aorto-iliac lumen to seal the AAA sac; a developing concept known as endovascular aortic sealing (EVAS). Conversion to open repair of AAA treated with the Nellix endograft have rarely been discussed. Explants that have been previously reported were for graft infection. We present two Nellix graft explants that were required for device migration and subsequent development of a type IA endoleak...

TEVAR is a well-stablished treatment of descending thoracic aneurysms and increasingly complex endovascular procedures are being performed including aortic arch and ascending aorta. However, follow-up complications may be expected, which will enhance the need of alternative approaches such as transapical, in case of complex anatomies and reinterventions. We report the case of a man with prior history of ischemic cardiopathy and multiple endovascular aortic interventions with proximal landing in zone 1 and distal landing proximal to celiac trunk...
